Ouli-Wolong MVE Standard Series Vibrating Motor (8-pole, 750rpm)

Manufacturer: Shaoxing OLI-Wolong Vibration Machinery Co., Ltd. (OLI-WOLONG), a joint venture between Wolong Electric Group Co., Ltd. (Stock Code: 600580) and Italy's WAM Group OLI Company. The company fully adopts Italian technology and manufacturing processes to specialize in level indicators, vibration motors, and vibration rods. OLI operates 19 sales subsidiaries, 36 warehouses, and 7 manufacturing facilities worldwide. Approximately 50% of its products are exported to Europe, the US, and other regions, establishing OLI as one of the world's leading manufacturers of vibration motors and pneumatic vibrators. Its three core product lines are industrial vibrators, flow aids, and concrete consolidation units. Series Positioning: The MVE Standard Series 8-pole models feature a synchronous speed of 750rpm, representing the lowest speed and largest single-travel amplitude within the series. At 50Hz, the excitation force ranges from 1 to 210kN with an output power of 0.08 to 18kW. At 60Hz, the excitation force covers 2 to 302.4kN. Frame sizes range from 40A0 to 120A0. Power supply is three-phase 220V~690V at 50Hz or 60Hz; special voltage and frequency configurations are available upon request. Structure & Manufacturing: Features a robust frame designed via FEM finite element analysis, vacuum impregnation, FMEA analysis, and 3D quality inspection. Insulation class F, protection rating IP66, continuous duty S1. Equipped with built-in PTC thermistors (130°C), special grease retention systems, and heat-resistant (tropicalized) treatment. Offers an optimal power-to-weight ratio and optimized electrical design. Bearings & Lubrication: Low-power models use specialized ball bearings pre-filled with lubricant for maintenance-free operation. High-power models utilize specialized cylindrical roller bearings pre-lubricated with sufficient grease; do not add grease before installation. Excitation Force Adjustment: Eccentric blocks are easy to adjust, categorized into Type A, Type B, and Type C. Type C uses sheet eccentric blocks with combinations of 5+5, 8+8, 9+9, and 12+12. Flipping up one sheet on each side reduces excitation force by approximately 40%, 25%, 22.2%, and 16.7%, respectively. Installation Requirements: The mounting surface must be flat with a flatness tolerance below 0.25mm to prevent shell stress and foot fracture during bolt tightening. Use high-strength bolts rated at least 8.8, nuts rated 8, and flat washers matching the hole diameter. Tighten to the specified torque. Mounting surfaces must be machined and painted-free. Electrical Connections: Verify voltage and frequency match the nameplate. Ensure power cables pass through cable glands and conductor cross-sections meet specifications. Green-yellow grounding wires must be reliably grounded. Before closing the terminal box cover, confirm the gasket is correctly positioned to maintain the protection rating. Overload Protection: All vibration motors require external overload protection devices. When two motors operate synchronously, each must have its own overload protection device linked together so that stopping one immediately stops the other. Certifications: CCC and CE certified.
